Kingdrilling diamond CO., LTD is one of the most professional private enterprise specialized in researching and producing casing drilling system, down the hole(DTH) hammer, down the hole bit, thread drill bits, taper drill bits, Anchor, coal mining tools and so on.
permanent ring bit casing drilling bits feature:
Permanent ring bit system is a concentric drilling system with retrievable pilot bits.
This system drills in any direction and in any type of ground condition.
The Symmetric components are made up of:
--- A pilot bits with large internal flushing holes and external flushing grooves
--- Symmetrical ring bit (reamer) with internal bayonet coupling
--- Casing shoe for driving of casing.
The Pilot bits is attached to any common DTH hammer shank.
